tracing: Select new NEED_TASKS_RCU Kconfig option
Currently, if a Kconfig option depends on TASKS_RCU, it conditionally does
"select TASKS_RCU if PREEMPTION". This works, but requires any change in
this enablement logic to be replicated across all such "select" clauses.
A new NEED_TASKS_RCU Kconfig option has been created to allow this
enablement logic to be in one place in kernel/rcu/Kconfig.
Therefore, select the new NEED_TASKS_RCU Kconfig option instead of the
old TASKS_RCU option.
